Application filed August 13, 1921.

To all whom it may concern: j

Be it known that 1, JOHN JAMES McCoivrisrr, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Pens, of which the following is a specification.

This invention relates to stationery, and has particular reference to an improved means for attaching a pen nib to or detaching a nib from a pen holder, making use of a process or method of attachment through which the nib may be. secured easily and quickly to the holder and firmly held in place for the usual purpose in such manner as to make its connection secure and sufliciently firm for the best and most sat thereof to the holder easy and reliable, and

a like, reference is had to the accompanying especially without any possible injury to theoperators fingers, and providing for the detachment of the nib from the holder at any future time with like facility and withfor the practical manipulation of the nib.

With the foregoing and other objects in view, but without restricting the invention unnecessarily as to materials, design, or the drawings, in which similar parts are referred to by like reference characters, and in which- Figure l is a dispersed view of the several main parts of the device.

Fig. 2 is aside view of the same assembled.

Fig. 3 is a longitudinal section of the holder carrying the locking device thereof in loose position ready for the reception of a nib. I

Fig. i is a detail view of another form of nib.

As indicated by the drawings my invention comprises two main parts,-a new type of nib and a holder particularly designed holder and remain attached thereto.

for co-operation therewith. The nib may be of various specific shapes but as indicated in Figs. 1 and 2 the nib 10 includes a shank portion having a pair of prongs 11 between which is a slot or opening 12. The prongs lie essentially or practically in a plane substantially at right angles to the length or axis of the main portion of the nib or the axis of the holder 13 constructed for co-op'eration therewith. As indicated the slot 12 is open at the bottom remote from the mainshank or body portion of the nib, andfrom the upper portion of the base or shank portion is a lug or projection 1% extending rearward at right angles to the base or prongs. This lugld may lie directly upon the surface of the holder or if preferred the holder may be formed with a depression 15 into which said lug may project.

The holder 13 in its broader aspects may be a cylindrical member of wood or the like having its lower end cut off flat and square or at right angles to the holder, and

in the center of such end is formed a hole 16 for the reception of a binding member shown in the form of a round headed screw 17 the head. of which is movable toward or from the end by a simple rotation of the screw toward the hole 16. Urdinarily the binding member will, be carried by the As thus described, with the screw loosened slightly from. the holder as indicated in Fig. 3, the prongs 11 may he slipped directly down between the head andthe end of the holder straddling the shank of the screw untilthe base or prong portion of the nib, whlch is practically circular, coincides with the end of theholder and with which it is from the holder to interfere with the manipulation thereof in writing or the projection thereof into a bottle or the like.

In some cases it is preferred to provide a cushion between the base 11 of the nib and the end of the holder, and to this end I provide a rubber disk or washer 18 of about the same diameter as the end of the holder and intended to remain secured in such position by any suitable means, such as a film of cement 19. in addition to the cement indicated in Fig. 3, the cushion may be secured auxiliarly by means of a ferrule 20 fitted upon the end of the holder and having a projecting flange 21 taking into the periphery of the disk 18. The outer face of the disk however projects suficiently far from the ferrule to permit the base portion of the nib to be plunged somewhat into the cushion while the clamping member 17 is being tightened. Some writers prefer the cushioning device, to afford a moderate amount of resiliency between the cushion and its holder. The provision of the lug let for the sake of others provides for reducing this flexibility of action between these parts. For maximum flexibility therefore I provide nibs as shown in F 4 in which the case 11 of the nib is made with only the. two prongs and without the lug 14.

The ferrule may be of ornamental metal if desired in the higher grades of holders, or it may be omitted entirely in the cheaper grades with very good satisfaction. The screw is provided preferably with a washer 22 of about the same diameter as the end of the holder so as to cover the slot or space 12 and the prongs. This washer may be separate from the screw or may be made as an integral part of the head. The base of the nib is gripped between said washer and the cushion 18 or end of the handle.

In the practice of this invention no matter how rusty or foul the pen holder may become from use or daubing with ink the nib may be easily and quickly removed simply by loosening the screw and allowing the nib Any convenient screw driver or other similar tool may be employed to turn the screw, and for the purpose of removing the used nib the operator needs never to touch it with his nngers.

day of October, 1922, SerialNo. 596,759.

I claim: 1. In awriting pen, the combmation of a holder having a flat end, a nib having a fiat base attachment portion substantially coexa llel prongs.

tensive in outline with said flat end against which it lies, and means movable lengthwise of the holder to grip the nib against the said fiat end.

In a writing pen, the combination of a holder having a flat end, a nib haying a flat base attachment portion to lie against the holder end, and a screw fitted in the holder and having a. head movable lengthwise of the holder against the [lat base portion of the nib to grip the nib against the Hat cud of the holder.

3. A device as set forth in claim 1 in which thebase portion of the nib comprises ,two spaced members lying in the same plane and the clamping means including a member projecting between said spaced members.

at. A pen holder having av flat nib-engaging end substantially perpendicular to its axis, and a cushioning member secured against said end.

5. A pen holder having an end, a pen nib having a base portion for co-operation with said end, and a threaded member movable at approximately a right angle to the nib base and longitudinally of the holder to grip the base of the nib against the end oi the holder.

6. A pen nib having an attachment base portion arranged substantially at a right angle to the length or axis of the nib, said base having an opening in its edge remote from the body portion of the nib.

7. A. nib set forth in claim (3 in which said base portion comprises two spaced par- 8. A nib as set forth in claim 0 in which said base portion includes a slitted structure through which a fastening member may be passed and also provided with :1 lug extending rearward from the base and at substantially a right angle thereto. said lug lying practically in alinement with the body portion of the nib.

9. A. pen comprising a holder having an end substantially perpendicular to its axis and formed with a depression adjacent to the end, a nib having a base adapted to abut against said end and also having a lug projecting into said depression, and a fastening member acting directly through said base into the holder for securing the nib de tachably thereto.

In testimony whereof I allix my signature.

JOHN J: Mccomsn.
